In reply to samnbuk:
How about a quickdraw to the bolt, clip it and turn into a clove hitch. Extra biner to the other bolt and belay device there in guide mode. When the second arrives to the belay, another draw to a bolt and clove hitch.
After which either can start the next pitch.
Those really safety focused could use lockin' biners instead of the draws. And if no tat or chain between the anchor bolts, well a quickdraw could be used to link the 2.
